Abstract
Disclosed is a gas turbine and a gas turbine power facility which flexibly accommodate changes in layout of devices and in user's needs. This invention includes an air compressor 1; a turbine 2 coaxially coupled to the compressor 1; a turbine casing 4 accommodating the compressor 1 and the turbine 2; a compressor output shaft 23 for coupling rotary devices including a power generator 200, the compressor output shaft 22 protruding from the turbine casing 4 towards the compressor 1; and a turbine output shaft 23 for coupling the rotary devices, the turbine output shaft 23 protruding from the turbine casing 4 towards the turbine 2.
Claims6
A gas turbine comprising:
- an air compressor,
- a turbine coaxially coupled to the compressor,
- a turbine casing accommodating the compressor and the turbine,
- a compressor output shaft protruding from the turbine casing towards a side opposite to the turbine,
- a turbine output shaft protruding from the turbine casing towards a side opposite to the compressor,
- a compressor side mounting section provided at a section of the turbine casing that is near the compressor;
- a turbine side mounting section provided at a section of the turbine casing that is near the turbine, and
- a rigid structure support member and a flexible structure support member that are used as a pair, wherein:
- only one of the compressor output shaft and the turbine output shaft is connected to a rotary device,
- the rigid structure support member is mounted to the compressor side mounting section or the turbine side mounting section, whichever is closer to the rotary device,
- the flexible structure support member is mounted to the compressor side mounting section or the turbine side mounting section, whichever is more distant from the rotary device, and
- the rigid structure support member is more rigid than the flexible structure support member.
